Uncertainty Analysis in Hydrologic Modelling

Hydrologic modelsHydrologic model differ regarding hydrologic processes, their parameters, inputs and outputs. Consequently, the results of different models for a particular period for a study area also differ. Uncertainty sources of hydrologic predictions are divided into three groups: uncertainties due to model parameters, uncertainties due to model structure and uncertainties due to observation data (for input and calibrationCalibration). Another source is the uncertainty generated from boundary conditions, i.e., scenarioScenarios uncertainty. Different uncertainty analysisUncertainty analysis techniques are reviewed and summarised to identify which is more appropriate for analysing a particular hydrologic modellingHydrologic modelling uncertainty. Finally, research prospects on uncertainty analysisUncertainty analysis of hydrologic modellingHydrologic modelling are proposed.
